Pre-college programming

[Fonzy0814]

I'm 16, live in Europe (Netherlands to be specific), got 2 years to go till college and am so far touched:
HTML (bah, hated it), javascript & java, PHP & C

Read all the basic books on each one, so not a specific area yet.
I have an older brother in college who said first year they did a lot with Data structures & Algorithmes. (He's also CS student obviously).
What do you recommend I go for and study, it's gotta be something around java, c(++) and those languages...nothing too hard yet obviously, but no easy stuff either.

Tips and books are extremely appreciated, thanks a mill in advance

depends on how in-depth you got with C. I would recommend using C (with WIN32 even) so that you can understand the "under-the-hood" stuff that you won't even touch later. Being aware of these things helps you become a better programmer.

C++ / Java are great because you learn the basics of OOP. Then move on to C# and smile every 10 minutes because you realize how cool the .NET framework is and how much it helps you.
